As a points-based green certification, LEED assigns 110 points – the highest level, platinum (80 + points), accredits only 3 out of a total of 110 points directly to embodied emissions. In BREEAM, 12 points (8%) are directly related to material selection, of which 5 points (3%) are based on life cycle assessment (LCA).  Studies using LCA to evaluate environmental impacts mainly consider operational emissions generated during the operation phase.  Initial (pre-use) embodied emissions are seldom the focus.  The number of points allocated to embodied emissions is disproportionately low in both the LEED and BREEAM building environmental (green) certification systems.
